Hi all,
I am newbie to javascript as well as Google Map API. I am trying to
plot multiple markers using Marker Manager and ProgressBar in my JSP.
Now, on Mozilla browser everything works fine, but on IE it gives me
this weird javascript error message. When I tried to debug the issue,
it routed me to main.js file of google maps and for a newbie its quite
difficult to understand the following code.
Ek.CacheEntry.prototype.ao=function(a){var b=this;b.Er=a;if(b.complete
())b.De=b.mb.L();delete b.mb;for(var c=0,d=j(b.tb);c<d;++c)b.tb[c]
(b);He(b.tb)};
The debugger stopped at this line. I am using Microsoft script editor.
Any help much appreciated. Sorry, I couldn't post link as its hosted
on an internal server inside organization.
Here's sample Javascript code.
